ROHO nexus SPIRI cushion - Manual (Page 8)

Step 5: Slide your hand beneath
your buttocks to locate your lowest
bony prominence,
usually the ischial tuberosities. If
necessary, your clinician or
caregiver should assist you.
Step 6: Leaving one hand in
place beneath the lowest bony
prominence, use the other hand
to open the valve. As air is
released from the cushion insert,
you will begin to sink into it.
When your fingertips touch its
base, close the valve.
Approximately 1/2" or 1.5 cm of
air should be between your low-
est prominence and the base of
the cushion.
IMPORTANT Adjustment Notes
• Your nexus SPIRIT Cushion may have been specially ordered with two
valves, one on each side of the cushion. If you have two valves, Steps 1 - 6
above should be repeated for each valve. Two valves indicate that your cush-
ion insert is divided in the middle. You or your clinician or caregiver should
locate the lowest bony prominence on the same side as the air valve used to
adjust the cushion.
• You, your clinicians and / or caregivers should check the cushion insert
daily to ensure that you have not bottomed out (ie. lost air and
sitting on the base of the cushion). If you bottom out, the protective value of
the cushion insert is lost. You should also check to be sure the cushion insert
is not over-filled with air. The cushion insert will work best with approximate-
ly 1/2" or 1.5 cm of air between you and
its base.
• The DRY FLOATATION cushion insert may be affected by changes in altitude.
You may have to repeat Steps 1 - 6 above as you
change altitudes.
